On 6 December1273 he experienced a divine revelation which so enraptured him that he abandoned the Summa, saying that it and his other writing were so much straw in the wind compared to the reality of the divine glory. He died four months later while en route to the Council of Lyons, overweight and with his health broken by overwork.

Charity is the form, mover, mother and root of all the virtues. - Saint Thomas Aquinas

We are like children, who stand in need of masters to enlighten us and direct us; and God has provided for this, by appointing his angels to be our teachers and guides. - Saint Thomas Aquinas

If you seek the example of love: “Greater love than this no man has, than to lay down his life for his friends.” Such a man was Christ on the cross. And if he gave his life for us, then it should not be difficult to bear whatever hardships arise for his sake. If you seek patience, you will find no better example than the cross. Christ endured much on the cross, and did so patiently, because “when he suffered he did not threaten; he was led like a sheep to the slaughter and he did not open his mouth.” If you seek an example of obedience, follow him who became obedient to the Father even unto death. “For just as by the disobedience of one man,” namely, Adam, “many were made sinners, so by the obedience of one man, many were made righteous.” If you seek an example of despising earthly things, follow him who is “the King of kings and the Lord of lords, in whom are hidden all the treasures of wisdom and knowledge.” Upon the cross he was stripped, mocked, spat upon, struck, crowned with thorns, and given only vinegar and gall to drink. Do not be attached, therefore, to clothing and riches, because “they divided my garments among themselves.” Nor to honors, for he experienced harsh words and scourgings. Nor to greatness of rank, for “weaving a crown of thorns they placed it on my head.” Nor to anything delightful, for “in my thirst they gave me vinegar to drink.” - from the writings of Saint Thomas Aquinas

The only-begotten Son of God, wanting to make us sharers in his divinity, assumed our nature, so that he, made man, might make men gods. - Saint Thomas Aquinas

Believing is an act of the intellect assenting to the divine truth by command of the will moved by God through grace. - Saint Thomas Aquinas

Most loving Lord, grant me a steadfast heart which no unworthy desire may drag downards; an unconquered hear which no hardship may wear out; an upright heart which no worthless purpose may ensnare. Impart to me also, O God, the understanding to know you, the diligence to seek you, a way of life to please you, and a faithfulness that may embrace you, through Jesus Christ, my Lord. Amen. - Saint Thomas Aquinas, from Something Of A Saint

Hence we must say that for the knowledge of any truth whatsoever man needs divine help, that the intellect may be moved by God to its act. But he does not need a new light added to his natural light, in order to know the truth in all things, but only in some that surpasses his natural knowledge. - Saint Thomas Aquinas
